  • Publication number: 20200074308
    Abstract: A solution is calculated using a tree search within a limited calculation time. A solution searching device that performs solution search using a search tree includes a search tree expanding unit that creates a node based on options until a stop condition is satisfied, an evaluation calculation unit that calculates an evaluation value for an leaf node using a first evaluation method, and a search solution determination unit that sequentially updates an evaluation value of an upper node based on an evaluation value of a lower node to determine a search solution.

  • Publication number: 20170063997
    Abstract: An evaluation apparatus includes: a processor; a memory; and an interface configured to receive data output by devices. The processor being configured to: receive action indicators including indicative data representing at least one physical quantity measured by a device and indicative data representing at least one specific of an action performed by the device through the interface; store the received action indicators to the memory; presume the action of the device by finding a match through comparing the received action indicators with templates each specifying a combination of items of indicative data required to presume an action of the devices; extract indicative data required to evaluate the presumed action from the received action indicators; and evaluate quality of the presumed action based on the extracted indicative data.
